SIGNAL-LIGHT.

SPECIFICATION forming part of Letters Iatent No. 787,740, dated April18, 1905.

Application led November 25, 1901. Serial No. 83,534.

T @ZZ whom it may concern.-

Be it known that I, EDGAR A. EDWARDS, a citizen of the United States,residing at Cincinnati, inthe county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Signal-Lights, of whichthe following is a specification.

My invention relates to that class of railway-signals combined withlocomotive-headlights set forth in Letters Patent to Samuel H.Harrington, No. 195,938, dated April 18, 1893; and my invention consistsof a certain improved arrangement of the supplemental reflector, asfully set forth hereinafter and as l 5 illustrated in the accompanyingdrawings, in

whichl Figure 1 is a sectional elevation of sufficient of alocomotive-headlight to illustrate my invention, and Fig. 2 is a planview.

2O The casing A and concave reflector C and lamp B of the headlight areof any usual or suitable construction. Within the reflector C isarranged a supplemental reector E, and

' this reflector E is so set that a portion of the 2 5 rays from thelamp yfalls upon the same and is reflected upward, and to permit them topass upward to constitute a signal of the proper character the reflectorC is cut away, forming an opening y, and the casing A is cut away,

forming an opening w, which preferably is closed by a glass plate c, soas to prevent the entrance of rain and snow.

The reflector E may be set permanently in its angular position to throwthe light-rays upward, and it may be curved so as to secure theparallelism of theserays when necessary;

but for signaling purposes, in order that it may be known that theengine is in motion, it is preferable to so support the reflector E thatit will be vibrated or rotated rapidly from the action of the engineitself-as, for instance,

by means of the belts and pulleys deriving their motions from one of therotating shafts t of the engine, as shown in Fig. 1.

Whe'n the reflector E is a flat plate, as 45 shown, it will offer butlittle obstruction to the light-rays when it occupies a longitudinalposition, as shown in full lines, and will reflect a portion of the raysdirectly upward when carried to the angular position. (Shown in dottedlines.)

The reiiector E may be made of any suitable material-as, for instance,`a metallic plate with polished surfaces, or it may be of transparentmaterial, as a plate of glass, in which case a portion of the light-rayswill pass through this plate and another portion will be reflected. I donot, however, claim, broadly, the combination, with alocomotiveheadlight, of a reflector of transparent material, as this isthe subject of a separate application for Letters Patent, Serial No.84,277, filed November 30, 1901, in which, however, the reflector isstationary and in some cases outside the case.

Without limiting myself to the specific construction and arrangement ofparts shown, I claim as my invention* The combination with the casingand stationary concave reflector C, having openings '70 for the passageupward of light-rays, of a snpplemental reflector within the reflectorC, and means for rotating the supplemental reflector, substantially asset forth. l

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

'EDGAR A. EDWARDS.
